Is it digital coaxial or optical audio?
Answers:
Your question is undeveloped. Optical or digital coax are types of connections not audio formats. They are relatively old and are two equivalent version (one optical and the other electrical) of the SPDIF connection (Link 1). But if you are discussion about connections you may be a sign of HDMI (High Definition Multimedia Media Interface) ... a single cable connection for giant definition digital video and multichannel audio (Link 2).
Advanced audio formats (relative to DTS and Dolby Digital) include Dolby Digital Plus, Dolby TrueHD and DTS-HD Master Audio used on Blu-ray or HD DVD disks.

HDMI 1.3 and 1.3a Cable and latest audio nouns is Dolby TRUHD and DTSMaster Audio When you use the "optical" or "coaxial" connection from your Blu-ray Disc (or HD-DVD) player, adjectives of that great (uncompressed) HD audio gets "watered down" to merely regular "Dolby Digital" or "DTS".
If you want your receiver to play any of the HD audio formats ("DolbyTrueHD", "DTSHD Master Audio" or "Uncompressed PCM"), after you'll have to use an HDMI cable or 6 to 8 individual RCA cable (one for EACH speaker, plus subwoofer).
